PUZZLE.

Speccation of Letters Patent.

YPatenten Dee. 1o, 1907.

Application filed March 23. 1907. Serial No. 364.205.

partment of schools in teaching the childrenl to become familiar with the use of numbers.

In the accompanying drawings forming part of this specification I have illustrated one form of my invention and in these drawings Figure 1 illustrates a complete card with the numbers arranged consecutively as when the puzzle. is worked out Fig. 2 illustrates the small cards with the numbers thereon said cards being cut apart and ready to bey assembled.

These cards may be made of any desired size and out of any suitable material, preferably card board, all of which are cut about an inch square. A diiierent number -is placed upon each side of each card. One of the cards which we will say for the purpose of illustration-has the number 33 on one side thereof and the number 10 on`thev other is cut in two so that on one side of each of the halfcards is. the figure 3 and on the other sides are the iigure one and the cipher respectively.

The numbers in the puzzle run from 1 to 36 and are so arranged that no two cards have the same numbers on both sides, and the numbers are all duplicated excepting the numbers 32 and 36.

When the` cards are all cut apart as shown use and one 26 is wanted for the last half of the game, the puzzle will be blocked until No. 26 is found and replaced by another card.

It will be found that by changing around the two halves of the card above referred to that live numbers can be formed, viz. 10, 13, 30, 31 and 33. This is intended to make the game. more complicated and for the reason that people try to do things the easiest way, an effort is naturally made to form the right number by changing these half cards into different numbers which can be formed as above explained and placing them in their the last row of numbers.

As before explained there is only one No.

32 'and one No. 36, and each of these two i 4numbers have No. 1 on the opposite side. 4 In beginning the puzzle by using card No. 1

with 32 on the opposite side, then there is no No. 32 to use when that number is wanted. If the puzzle is begun with the card that has No. 36 on the opposite side there will be no card having 36 to use as the last number, but by forming another 32 with the half cards as above explained then the puzzle can be Iput together easily.

claim:

1. A puzzle comprising a set of cards having the numbers from one to thirty six, each of said cards having a diHerent number upon' each side thereof, all of said numbers but two being duplicated, and two ofsaid c'ards being half the size of the remaining cards, substantially as described.

2. A puzzle comprising a set of cards, each of said cards having a different number upon each side thereof, all of said numbers but ltwo being duplicated, two of said cards being half the size of the remaining cards, said half sized cards adapted to be placed upon each side of a whole card to form two new numbers, substantially as described.
